Conventional epidural catheters used in performing neurolytic blocks create frequent problems such as kinking, misplacement, and questionable localization of the catheter. We present a study of a new epidural catheter for injection of phenol in patients with severe pain problems. In four of five cases complete pain relief was obtained for several months. The design of this catheter provides improved localization of the injection site.
